Answer 1

To find the area of a triangle, you can use the formula:

\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \]

From the information given, it looks like we need to identify the base and the height. The two provided numbers are 15 mm and 9 mm. Typically, in such problems, these two numbers are the base and the height of the triangle.

Let's assume:
- Base (\( b \)) = 15 mm
- Height (\( h \)) = 9 mm

Now, plug these values into the formula:

\[ \text{Area} = \frac{1}{2} \times 15 \, \text{mm} \times 9 \, \text{mm} \]
\[ \text{Area} = \frac{1}{2} \times 135 \, \text{mm}^2 \]
\[ \text{Area} = 67.5 \, \text{mm}^2 \]

However, this doesn't correspond to any of the provided options directly (54 mm², 24 mm², 141 mm², 70.5 mm²). This suggests there may be a misunderstanding or more information needed from the context.

Given this information, the closest answer is likely 70.5 mm², but rounding 67.5 mm² to 68 mm² doesn't match exactly.

Double-check the problem image and context. Also, ensure any assumptions made about base and height match the diagram.
